In this post you will learn about the replacing capacitor in ceiling fan. Ceiling fan numbering in those electric appliances and machines which we use very much in our life and mostly in summer season. In AC fan we have two types of internally winding which called main winding and starting winding. Most people know main winding with the name of running winding and starting winding as auxiliary winding. However in this post we only high lights the procedure of replacing capacitor in fan.


Replacing Capacitor in Ceiling Fan Motor or other Fan Motor

When your fan running slow or not running and make a type of sound then maybe your fan winding problem or capacitor but mostly this problem comes with capacitor. I also publish a post about role of capacitor in fan and you can learn by using the below link.

So we use capacitor with fan but when capacitor become week, our fan RPM or speed become slow or if the capacitor stop his duty totally or blown then our fan stop running. Note that in some case the fan slow due to the Dimmer switch which we use for ceiling fan to regulate the speed. So if your fan running slow then first chick your dimmer switch , may be some one regulate it on slow direction. However fallow the steps before you gonna to change your capacitor in fan.

  1. First of all switch off your supply from your main DP board
  2. Then open connection point of fan where the capacitor instilled from company
  3. Then check the capacitor value and buy the same value capacitor from market or online store.
  4. Now remove the old or blown capacitor wire one by one and connect these wire to new capacitor.
Note that change the same ratio capacitor to fan. If a fan have 2 uf capacitor then replace a 2 uf capacitor to fan.
After replacing capacitor fix all thing and start your supply form Distribution board and check the fan, if ceiling fan running slow or still fan is not starting change the dimmer switch and after that if fan have same problem. Then this may happen in case of following problem.

  • Your fan main winding or starting winding is burn if fan still make sound and not starting. Or the fan bearings is jam.
  • If the ceiling fan not staring and have no making sound or vibration then may be your fan internally winding is burn or cut ( open circuit).
  • OR your in coming supply is not receiving to the fan. 
Now If your fan not starting and have no sound then conform that the current supply is receiving to fan , so if fan receiving the current and still not working and not making any type of sound then may be your fan internally winding is cut (open circuit)/ burn. Or maybe it's connection wires are cut.


Now come to explain it using a simple clip art replacing capacitor in ceiling fan diagram. In this below diagram i shown the ceiling fan motor and it's connection point where the capacitor instilled. For example your fan capacitor is blown and you want to change it with new one, then the first option to check the number of old capacitor. It's for that reason that you buy a new capacitor with same model and ratio. Now if your fan capacitor have 3 wire red, yellow and purple. So if all wire are connect to fan other wires then buy same type of capacitor and if your fan old blown capacitor have three wire and only two is connect to the fan wiring then follow these step.

  • First of all buy the same type of capacitor form market.
  • And if the same type of capacitor is not available then check the capacitor value. You will find that there two types of value written on capacitor. For example 1.2 micro farad and 2.3 micro farad . You will see that the red and yellow wire capacitance value is 2.3 uF and red and purple wire value is 1.2 uF. So your common wire is red. I also shown the 3 wire capacitor diagram inside the below ceiling fan capacitor changing diagram
  • Now if the red and yellow is connect to the fan then buy a 2.3 uF capacitor form market and connect it to the fan.
The all process of replacing capacitor in ceiling fan i shown in the below diagram which help you in understanding.


replacing capacitor in ceiling fan

In the above replacing capacitor diagram i shown three wire capacitor, it's for that if you required a 2.3 uF capacitor and which is a two wire capacitor and in market the two wire capacitor is not available then buy a three wire capacitor which have a value of 2.3 micro farad. And connect the 2.3 uF wire to the fan a leave the other wire as i shown in the above diagram. Note that insulate the other wire.

Replacing 3 Wire Capacitor to Fan Motor In Speed Control Switch

If your fan motor is working on three wire capacitor and it's connected to the fan speed control switch then connect the connection as shown in the below diagram and also read the post which i given after below replacing 3 wire capacitor to fan diagram.

In this  post i am gonna to tech you about ceiling fan speed control wiring diagram, from which you easily learn fan speed regulating speeds. In this post i am gonna to share speed controller diagram with low, med and high speed diagrams. On thing more i also shown in the below that how can we control the speed of fan motor using 3 wire ceiling fan capacitor. One thing more we can also use dimmer switch for regulating speed of ceiling fan. However in my last most i shown 5 wire ceiling fan capacitor diagram, in which i also shown a speed controller diagram using speed control switch diagram.

Ceiling Fan Speed Control Wiring Diagram


First of all i want to clear you that we can control the fan motor speed using 3 method in which we can do the ceiling fan motor speed control using two methods, while in stand fan motor we can also regulate the speed by doing the connections in axillary winding / starting winding. For ceiling fan speed controlling we use mostly two methods in which on is by using speed control using three or five wire capacitor. And other one is using a dimmer switch from which we can control the RPM (revolutions per minute) of ceiling fan or other fan motor.
So First we talk about ceiling fan speed wiring diagrams, which i designed 4 diagram in which i shown Off , low , med and high speed direction of fan motor speed switch controller. Here is the fan speed low, high and med speed direction diagram,

ceiling fan speed control diagram


So As you know that by using 3 wire capacitor, we can control the speed of motor using speed regulator switch. So in the the above diagram i shown the switch in 4 types of diagrams. So for example our fan capacitor is 3 wire capacitor red, yellow and purple. So yellow for 1.5 uF and purple for 2.5 uF. So here is an complete diagram in which is shown the ceiling fan motor main winding and auxiliary winding / starting winding with speed controller switch, capacitor and AC supply. In the below ceiling fan speed control switch diagram i shown the fan speed switch knob on off direction.
ceiling fan speed control wiring diagram


In the above ceiling fan speed control wiring diagram i shown the main winding / running winding and i connect run wire of motor to the speed control switch and you can see it in above diagram that connection of run wire of motor in switch L point and and 1 and 2 for capacitor. I connect Purple color wire of capacitor to 2 terminal of speed Controller which 2.5 micro farad and 1.5 uF to 1 point of speed which yellow wire of capacitor. And red is common wire of capacitor and i connect this wire to start point of fan.

On thing fore the phase (line) wire to 3 point of switch and neutral to common wire fan motor. So in the above diagram the switch contacts on L to 2 it's means that  the 3 wire current is not connect to fan and fan is off.
So lets see the low speed wiring diagram of fan.

ceiling fan speed control switch wiring diagram
So in the above diagram the fan speed regulating switch contacts on L, 3 and 1 side and the line current is start to run wire of fan and 1.5 uF and the fan on low speed. lets see the fan on med speed.

So in above diagram the speed switch contacts on L , 3 and 2.5 uF and fan on running or start on 2.5 micro farad Cap and on med speed. Now lets see the High speed of fan diagram.

fan motor speed control wiring diagram

So in the high speed direction of speed controller switch the all contacts are connect with one another, and both 1.5 uF and 2.5 uF are connect to the motor, it's means that 1.5 + 2.5 is 4 uF capacitor is connected to the fan motor. So high capacitance number of capacitor is connected to fan motor and fan motor run fast on high number of capacitor which 4 micro farad. One thing more that don't connect too high value capacitor which is out of fan motor range. For example if a motor required 4 uf capacitor and you connect a 10 micro farad capacitor then the result will be bad and fan motor winding will be burn.

Fan controlling Speed Using Dimmer Switch

This is another method of controlling speed of ceiling fan, in which we use a dimmer switch from controlling or regulating speed. For better understanding about wiring connection of dimmer switch read the below posts.

In this post i am writing about the 5 wire ceiling fan capacitor wiring diagram, in my last post i written about the 3 wire capacitor diagram which we use for fan and can regulate speed by using speed controlling switch. Now in this you will learn about ceiling fan 5 wire capacitor and it's diagram.

5 Wire Ceiling Fan Capacitor Wiring Diagram

In ceiling fan we use the 5 wire capacitor for speeds, low Med and High speed. On this type of capacitor we have five wire in which two is common and 3 other for different value capacitance micro farad.
In the below diagram i shown a 5 wire fan motor capacitor with it;s capacitor diagram.

5 wire ceiling fan capacitor wiring diagram

In the above diagram i shown an image of fan motor capacitor which CBB61 and it's a 5 wire capacitor, the two gray wire are common and red is 4.5 uF 250V and Brown is 6 uF 250 Volts and Purple is 5 micro farad and 250 V.

Mostly we use this type of capacitor for speeds, as i told in my above words, so here is an diagram form which you can get idea of using this capacitor. in the below diagram i shown how can we regulate fan speed. Here i shown a diagram in which i shown a ceiling fan main winding / running winding and auxiliary / starting winding with capacitor with speed controller / selector switch and one way switch with low , med and high speed.
5 wire ceiling fan capacitor wiring diagram with fan speed controller
In the above diagram i shown AC supply and i connect the neutral wire to motor winding (common winding point) and the phase (Hot wire) connect to the one way switch and form switch connect to the motor main winding and capacitor all wires of capacitance which is 4.5 uF, 4 uF and 6 micro farad. and you can see that speed selector switch on low direction and when it;s switch move on the 5 uF," the ceiling fan will be on med speed and on 6 micro farad the speed will be high. This is an basic diagram of 5 wire ceiling fan capacitor wiring diagram and it's working.
Now if you have an question regarding this post ceiling fan wiring diagram 5 wire capacitor then you can tell me in below comments section.

As you know we use single phase types motor in ceiling fan and a ceiling fan required capacitor to run. In ceiling an we use capacitor, in which one type capacitor have 3 wire. In this post i am gonna to explain the ceiling fan 3 wire capacitor wiring diagram. This capacitor have 3 wires in which one is common for both and other two for different value capacitance. My means that there are two capacitor instill in this capacitor and both value is different from one another.

Ceiling Fan 3 Wire Capacitor Wiring Diagram

The 3 wire fan capacitor diagram mostly available on capacitor but most people did not understood. And he always try to buy a 2 wire fan capacitor. But the 3 wire capacitor is better than 2 wire because we can use if for two different requirements.
In this capacitor one wire is common and between common wire and 2nd wire the capacitor is different then between common and 3rd wire.
One thing more in some ceiling fans we use this type of capacitor for regulating speeds. I.e example that form example when the fan motor start on 1.5 uf the motor will be on low speed and when the capacitor on 2.5 then the motor will be on med speed and when ceiling fan motor run on both capacitor in same time (1.5 + 2.5 = 4 uf) then the motor on high speed.  And as i told in my above words that we can use it for a fan motor which only required the 1.5 micro farad capacitor.
However ceiling fan 3 wire capacitor we use in fan for mostly for speeds. In fan we use speed regulator switch form which we can regulate the speed using capacitor.
We have 3 wire is ceiling fan capacitor in which red is common and other two are for different capacitors values.

As you know that there are different types of circuit breaker , in those circuit breaker a well known name is mccb which molded case circuit breaker and in this post you will learn about the mccb wiring and initiation. in this post i am gonna to share with you two diagram of mccb in which one is about the wiring of 3 pole mccb circuit breaker and other one is about 4 pole circuit breaker.
By using the the three pole circuit breaker we can control three phase power system and by using the four pole we can control 3 phase 4 wiring system. However i also share diagram about the wiring and instillation of MCB (miniature CB) and you can also read about those diagram and post by using the following links.

How to wire Three Pole and 4 Pole MCCB circuit breakers


The wiring of mccb and mcb circuit breaker is same, and it's too simple but the difference between in mcb (miniature CB) and mccb is that we can use mcb the load between 0.5 to 100 amps and range of ampere of mccb is 1000 amps.
So if are doing a connection for distribution board which ampere is over then 100 ampere then we can not use the mcb and we must instill the MCCB.
The three pole type of molded case circuit breaker are use mostly for controlling the three phase system and this also design for that work. However we can use it for any work regarding work. If our single phase load is over than 100 ampere than we can also use this circuit breaker.
In the below mccb wiring diagram i show the complete method of wiring and installation of three pole molded case circuit breaker.

mccb wiring diagram


When we have to control a 3 phase circuit by using a breaker the first option to chose a three pole but if the circuit is three phase 4 wire system then this work can not be done with out a 4 pole circuit breaker. In the below 4 pole mccb control wiring diagram i shown the complete method of instillation and wiring of 4 pole molded case CB.

4 pole mccb wiring diagram


On thing more that if you are gonna to wire a multi storey building and instillation  three phase 4 wire system then use mccb in your main distribution board but chose your breaker regarding your total load. However further soon i will will publish post about wiring instillation in multi storey building diagrams and a guide in which i will also do the mccb wiring connection.
